ABSTRACT:
An apparatus and method for reducing the dynamic range of input numbers representing a physical quantity by producing a sample set of sample numbers representing a representative sample of the physical quantity and for each sample number, determining a corresponding nearest mapping weight from a plurality of mapping weights of a mapping function. The corresponding nearest mapping weight is increased or decreased in proportion to the arithmetic difference between the corresponding nearest mapping weight and each sample number in the sample set. Then, each successive input number, is applied to the mapping function to produce a corresponding output number. There is also disclosed a processor readable medium on which is stored a set of instructions operable to direct a processor to perform the method.
